V.I. Lenin's Tactics...What were they? Short facts please.?

Umm..I need help with an essay. The topic is "Who was a more effective leader? Gandhi or Lenin?" I chose Gandhi because he used nonviolence and resistance rather than Lenin's tactics of violence and propaganda. Now some of the tactics Gandhi used, in more detail, were events like the Salt March and boycotts and civil disobedience-all peaceful tactics. What tactics did V.I. Lenin use? Can I have short facts or words like I did with Gandhi's?
